Frequency of System Software Updates on Automotive Devices
Garmin releases system software updates periodically. Although there is no set time frame for software update releases, it is recommended to check for updates periodically to ensure your device stays up-to-date. To check for updates, you may use Garmin Express.
To update, your device must be connected to the computer for the application to check for and install system software updates. System software updates are released more frequently for newer models. Older models are not updated as frequently and usually only when a map update is released or a new feature added. Once the application is installed it can be opened periodically to check for system software updates.
It is recommended to create a backup of the favorites on your device prior to updating the software. For instructions, see Backing up, Restoring, or Transferring Saved Data on Garmin Automotive Devices
